Yeah .com.co isn't that strong.
Doctorsportal.com could be a low
4 figure. Good for medical advice, medic forums or a site where doctors could connect, studies etc etc. I see potential in it
Kick them on Sedo, Afternic, Flippa, Namepros etc. Just see what bids are coming in. Never know what someone pays for it. But looking at it again it has potential and you have a strong name in hands!
